So before starting work, make a record of the contents in the audio memory system. * Pop up hood lifter assembly * Curtain shield airbag assembly * Do not expose the following parts directly to hot air or flame; * * Knee airbag assembly Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair. After work on the SRS is completed, check the SRS warning light. * Rear airbag sensor assembly * Front passenger airbag assembly Work must be started more than 90 seconds after the engine switch is pushed to the "OFF" position and the negative (-) terminal cable is disconnected from the battery. * * Rear seat airbag assmbly * Front airbag sensor assembly * If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual. However, it is not possible to make a record of these memory contents. So when the work is finished, it will be necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. * Side airbag assembly * NOTICE : When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions and the procedure, and precautions in the Repair Manual applicable for the model year. To avoid erasing the memory in each system, never use a back-up power supply from outside the vehicle. Never use SRS parts from another vehicle. When replacing parts, replace with new parts. * Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected; * Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system. (The SRS is equipped with a back-up power source so that if work is started within 90 seconds from disconnecting the negative (-) terminal cable of the battery, the SRS may deploy.) * * * Steering wheel pad When work is finished, reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function. * * * * Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery. For the purpose of reuse, never disassemble and repair the following parts. If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector, replace with new one. * Pedestrian protection sensor * Center airbag sensor assembly Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice. * Door side airbag sensor assembly Y Y-B Y-G Y-R Y Y-B Y-G Y-R Y Y-B Y Y-R Y-G B Y-B BR BR Y-B Y Y-B Y Y Y-B (*1) (*1) (*1) BR BR P+ P- P2+ P2- 2 B 1 B 2 A 1 A Y1(A),Y2(B) Instrument Panel Passenger Airbag without Door Assembly 1 B 2 C C 1 B 2 z2(B),z3(C) Driver Side Squib Circuit (Horn Button Assembly) D+ D- D2+ D2- 3 A 1 A 2 A 4 A Spiral Cable with Sensor Sub-Assembly K31(A),z2(B),z3(C) 10 A DK- 7 A D2- 19 A PK+ 20 A PK- 4 A P+ 16 B SRR+ 3 A P- 15 B SRR- 25 A E1 1 A P2+ 2 A P2- 9 C SRL+ 10 SRL- 21 A IG2 26 A E2 5 A D+ 9 A DK+ 6 A D- 8 A D2+ K51(A),P31(B),Q9(C) Airbag Sensor Assembly 2 SRR+ 1 SRR- P12 Rear Seat Airbag Assembly RH (Rear Side Seat Back Assembly RH) 2 SRL+ 1 SRL- Q21 Rear Seat Airbag Assembly LH (Rear Side Seat Back Assembly LH) Knee Airbag PK+ PK- 1 2 Lower No. 2 Instrument Panel Airbag Assembly K53 Knee Airbag DK+ DK- 2 1 Lower No. 1 Instrument Panel Airbag Assembly K48 7.5A A/BAG-IG2 4A 8 2 (IG) 4A 47 4A 9 4A 45 4A 37 1 2 3 4 Y-B Y Y Y-B W B W B W B W B Y-B Y B Y R W B Y R W Y Y-B (*1) K51(A),P31(B),Q9(C) Airbag Sensor Assembly C 30 A +SL 28 A -SL 24 B BBR+ 23 B BBR- 29 A +SR 27 A -SR 17 C BBL+ 18 C BBL- 5 C ICL+ 4 C PL+ 6 C ICL- 3 C PL- 4 B ICR+ 5 B PR+ 3 B ICR- 6 B PR- 1 ICR+ 2 ICR- Curtain Shield Airbag Assembly RH P15 1 ICL+ 2 ICL- Q24 Curtain Shield Airbag Assembly LH 2 +SR 1 -SR Front Airbag Sensor RH A8 2 +SL 1 -SL Front Airbag Sensor LH A43 R+ R- Pretensioner 1 2 P10 Front Seat Outer Belt Assembly RH Pretensioner L- L+ 1 2 Q19 Front Seat Outer Belt Assembly LH 1 BBL+ 4 BCL+ 2 BBL- 3 BCL- Q22 Rear Airbag Sensor LH 1 BBR+ 4 BCR+ 2 BBR- 3 BCR- P13 Rear Airbag Sensor RH 2 BBL+ 1 BBL- Side Airbag Sensor Assembly LH Q18 2 BBR+ 1 BBR- Side Airbag Sensor Assembly RH P9 1 2 1 2 * 1 :w/ Rear Side Airbag Y-B Y L G Y-B Y (LHD) Y-B Y Y-B Y Y-B (LHD) (LHD) (LHD) LG R LG R G L G L (*5) (*5) (*5) (*5) Y Y-B Y K51(A),P31(B),Q9(C) Airbag Sensor Assembly 1 C PLR+ 12 C PUL+ 2 C PLR- 11 C PUL- 8 B PRR+ 20 C PSL+ 7 B PRR- 19 C PSL- 16 C LSP+ 1 B SFR+ 2 B SFR- 24 C LSP- 15 C LBE+ 8 C SFL+ 23 C LBE- 7 SFL- 2 PLL+ 1 PLL- A45 Pop Up Hood Lifter Assembly LH 2 PSL+ 1 PSL- Pedestrian Protection Sensor LH A44 RL- RL+ Pretensioner 1 2 Q23 Rear Seat 3 Point Type Outer Belt assembly LH RR- Pretensioner RR+ 1 2 P14 Rear Seat 3 Point Type Outer Belt Assembly RH LBE+ LBE- Buckle Switch Seat Position Airbag Sensor LSP+ LSP- 4 3 2 1 Front Seat Airbag Assembly LH Q13 SFL+ SFL- 1 2 Front Seat Airbag Assembly LH p1 SFR+ SFR- 1 2 o1 Front Seat Airbag Assembly RH 2 3 1 4 1 2 1 2 Y W B W G B Y-B B (*3) (*3) (*2) (*2) (*2) (*2) B Y-B R G Y-B Y (RHD) (RHD) (RHD) (RHD) (*4) (*4) (RHD) BE BE L B W L B W Y-B K51(A),P31(B),Q9(C) Airbag Sensor Assembly 13 A CANH C 11 A MSW+ 9 B RSP+ 12 A MSW- 17 B RSP- 17 A P-AB 10 B RBE+ 18 B RBE- 23 A PAON 13 B PUR+ 18 A GSW 14 B PUR- 24 A GSW3 21 B PSR+ 22 2 PMC+ 1 PMC- Airbag Cut Off Switch Cylinder Sub-Assembly K98 24 A GSW K66(A) Telematics Transceiver P-AB PAON PASSENGER AIRBAG ON/OFF Indicator 12 13 A/C Control Assembly K65 Main Body ECU GSW RBE+ RBE- Buckle Switch Seat Position Airbag Sensor RSP+ RSP- 4 3 2 1 P4 Front Seat Inner Belt Assembly RH 2 PLR+ 1 PLR- A10 Pop Up Hood Lifter Assembly RH 2 PSR+ A9 Pedestrian Protection Sensor RH 24 7 4A 17 4A 25 4A 48 4A 46 4A 38 4A 26 4A 2 3 1 4 * 4 :w/ Airbag Cut Off Switch * 2 :w/ PASSENGER AIRBAG ON/OFF Indicator * 5 :w/ Rear Pretensioner * 3 :w/ Telematics Transceiver B R B L LG B B R (RHD) B (LHD) B (LHD) (RHD) B (RHD) BE (LHD) BE (LHD) B G G B (LHD) B (RHD) BE (LHD) BE (RHD) B (LHD) B (RHD) BE (LHD) BE (RHD) 22 A CANL B PSR- 5V IC Telltales LED Driver CAN I/F ES CANL CANH B IG+ CPU CPU 5V+B 30 A 29 A 21 A 22 A 31 A Combination Meter Assembly K3(A) 1 PSR- 13 26 A B CANL 14 13 B A CANH A77(B),A91(A) ECM 4 14 11 12 1 2 No. 1 CAN Junction Connector K109 11 1 15 5 3 13 No. 2 CAN Junction Connector K110 7 20 (*6) (*7) * 8 :w/ Stop & Start System * 7 :8AR-FTS * 9 :w/o Stop & Start System * 6 :2GR-FSE, 4GR-FSE K3(A) Combination Meter Assembly LG LG LG B BR BR GR (*8) (*9) (BAT) 2 1 10A MPX-B NO.1 10 C IG12 Engine Stop and Start ECU K139(C) 4C 32 4B 30 7.5A METER 2 (IG) 4A 53
